I would say that in combination with a moderate rim size (R18), run flat, sports running, but at the same time, soft rubber, it turned out to be just the perfect mix. Not soft and not hard, not noisy, but not quiet, not harsh, but not gross. Overall: So far, the feeling of any tire that I have ever had is incomparable. In short, cool sensations, really very similar to the five E60. . An interesting observation: the higher the speed, the better the rubber is controlled!) Directional stability in a straight line is amazing, it just seems to stick to the asphalt. Turning radii, yes, have increased somewhat (softness affects), but she does not try to jump off him, but keeps straight in him, hard and weighty. Braking is a complete fly away, again, softness affects. In general, I was shocked at how she goes in a straight line. Very cool. Perhaps even better than the E60 in some ways. Perhaps I just got used to the fact that it turns out that the car can drive in a straight line, and not as it pleases, and does not try to jump off every bump)) And it also seems to me that sports tires a la Potenza, P Zero and others like them are really not for our roads. For these types of tires, IMHO, you need absolutely perfect asphalt, otherwise it’s easy to get on them on any more or less bumps. You will just be stressed all the time. In general, I would say so. This rubber is not that soft, it is rather very elastic. And on the steering wheel there is precisely a clear understanding of what is happening under the wheels. Elastic and "heavy" feedback. You just understand what's going on. (On Potenza, sometimes the soul in the heels went away from the rut and throwing along the road). Accordingly, there are no permanent nerves. I'm out of the habit of this feeling of calmness in the car, and these tires give it. I purchased Italian-made RunFlat tires with an index of 100Y (not W) in BMW homologation (*).
